SHEET-IVI ETAL. SHELF-BRACKET.

SPECIFICATION forming part of Letters Patent No. 581,980, dated May 4,1897'. Application ned December 11,1393. serai No. 493.380. (No man i Toa/ZZ whom, t may concern:

Be it known that I, THOMAS ConscADnN, of New Britain, in the county ofHartford and State of Connecticut, have invented a new Improvement inSheetaMetal Shelf-Brackets and I do hereby declare the following, whentaken in connection with accompanying drawings and the letters ofreference marked thereon, to be a full, clear, and exact description ofthe same, and which said drawings constitute part of this specification,and represent, in-

Figure l., a View in side elevation of one form which a shelf-bracketconstructed in accordance with my invention may assume; Fig. 2, a viewin front elevation Fig. 8, a plan view.

My invention relates to an improvement in sheet-metal shelf-brackets,the object being to produce a cheap and strong bracket of attractiveappearance with the least expenditure of material and labor.

With these ends in view my invention con sists in a sheet-metalshelf-bracket composed of three non-integral elements-namely, wall andshelf plates, ribs, and a brace-all of the said elements being adaptedto be secured together in the manner shown and described.

As shown in the drawings, the wall-plate and the shelf-plate AQ formingone element of the bracket, are formed from a single strip of sheetmetal bent transversely a little to one side of its longitudinal center,the wallplate A having countersunk perforations d for the attachment ofthe bracket to the wall, and the shelf-plate having correspondingperforations a for the attachment of the shelf to it. The ribs B and Bof the bracket form another element thereof. As herein shown, they aremade independent of each other, their meeting ends being miteredtogether on the line h. If desired, however, the two ribs may be madeintegral with each other, but

that construction is not so economical of material, as there is somewaste in cutting out the ribs in that way. In 'case the ribs are madeintegral the wall and shelf plates might be made non-integral and lockedtogether at their meeting ends or simply abutted. The rib B isconstructed, as shown, with three lugs Z9', which are passed throughcorresponding lug-openings a2, formed in the wall-plate A, the outerends of the said lugs being headed down, whereby the rib B is rigidlysecured to the inner face of the wall-plate at a right: an-

gle thereto. The rib B is furnished with three lugs h2 b2 h2, which arepassed through corresponding lug-openings a3 CL3 a3, formed in theshelf-plate, the outer ends of the said lugs being headed down torigidly secure the 6o rib B to the shelf-plate.

The other element of my improved bracket is a brace C, longitudinallybowed and having its ends rigidly connected with the respective ribs Band B', for which purpose 65 each of the said ends is constructed withan undercut lug C', adapted to take into corresponding undercut slots B2B2, formed in the respective ribs with which the ends of the brace arethus interlocked. y

To bind the ends of the brace to the ribs against lateral displacement,Iemploy two transverse pins D D, each of which is furnished at each endwith a washer E. The said pins are passed through the ribs and the lugsThe washers are held 8o tion herein shown and described, but hold myselfat liberty to make such changes and alterations as fairly fall withinthe spirit and scope of my invention.

A bracket constructed in accordance with my invention is very easy toassemble and 9o economical of metal, as there is very little waste incutting out parts of the shape called for. When made, it is stiff andeffective and presents a tasteful appearance.

I am aware that sheet-metal brackets are old, that it is old to form awall and shelf plate from a continuous strip of metal, and thatcast-metal brackets having three members or elements are old, and I donot claim any of those constructions broadly; but,

IOO

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a sheet-metal bracket, the combination with wall and shelf platesConstructed with 1ugopenings, of sheet-metal ribs formed independent ofthe said wall and shelf plates and constructed with integral,outwardlyprojeeting lugs arranged in correspondence with the saidlu:,r-OpeI1in ;siny the plates, to which the ribs are rigidly secured byupsetting the outer ends of the said lugs; a brace made independent ofthe said Wall and shelf plates and the ribs, and having,` its outer endssecured to the ribs, and transverse pins and washers applied to the endsof the brace and to the ribs, for holding the ends of the former againstlateral displacement, the said pins and washers being independent of thewall and shelf plates.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

THOMAS CORSCADEN.
